Analysis of Disruption Scenarios and Their Possible Mitigation in ITER
Database analyses have been carried out to derive physics guidelines for the shortest current quench time and their waveforms as well as the product of halo fraction with toroidal peaking factor arising from disruptions in ITER. Several representative disruption scenarios are specified. Disruption simulations with the DINA code and electromagnetic load (EM) analyses with 3D finite element metho...
متن کامل1 IT / P 6 - 19 Pellet Fueling , ELM pacing , and Disruption Mitigation Technology Development for ITER ∗
Plasma fueling with pellet injection, pacing of edge localized modes (ELMs) by small frequent pellets, and disruption mitigation with gas jets or injected pellets are some of the most important technological capabilities needed for successful operation of ITER. Tools are being developed at Oak Ridge National Laboratory that can be employed on ITER to provide the necessary core pellet fueling an...
متن کامل1 ITR / P 1 - 27 Shattered Pellet Disruption Mitigation Technology Development for ITER
The mitigation of first wall thermal and mechanical loads and damage from runaway electrons during disruptions are critical for successful long term operation of ITER. Disruption mitigation tools based on shattered pellet injection are being developed at Oak Ridge National Laboratory that can be employed on ITER to provide the necessary mitigation of thermal and mechanical loads from disruption...
متن کاملELM physics and ELM mitigation in ITER
Edge Localised Modes are characteristic of the high performance, H-mode plasmas that are required for the attainment of Q = 10/500MW fusion power in the first phase of ITER operation. The energy released by a type I ELM, in good confinement plasmas, is typically 510% of the plasma stored energy; with low collisionality plasmas at the upper end of the range. Dimensional analysis, experiment and ...
متن کاملDisruption Characterization and Database Activities for ITER
Disruption characterization and database development and analysis activities conducted for ITER under the aegis of the International Tokamak Physics Activity (ITPA) Topical Group on MHD, Control and Disruption are described. Accomplishments during 2005-2006 include: (1) formation of an International Disruption Database (IDDB) Working Group, (2) implementation of an MDSplus-based IDDB infrastruc...
